Even by Mitt Romney’s gaffe-tastic standards, this was a bad one. Speaking at a Republican luncheon in Ames, Iowa over the weekend, the Massachusetts governor and would-be Republican presidential nominee referred to the Big Dig as a “tar baby” — a phrase which, though sometimes used to describe sticky situations, is also a pejorative term for African-Americans.

There's a certain just-desserts quality to this latest Romney stumble, since the governor has been unseemingly eager to fold his newfound control of the Big Dig into the whole “Turnaround” narrative. Consider the offensive quote in question: “The best thing for me to do politically is stay away from the Big Dig — just get as far away from that tar baby as I possibly can.” Mitt, that’s a load of crap. You know — and everybody watching you knows — that this is a golden opportunity: you can brag about taking control of the project, but you’ll be back in Utah (or Michigan) in a few short months, leaving the next governor to muddle through.

In addition to pointing up the governor’s fondness for shameless self-promotion, what else does this gaffe tell us? For starters, he doesn’t follow the news too closely. (Earlier this year, White House spokesman Tony Snow’s use of the “tar baby” term sparked a very public controversy.) What’s more, Romney probably doesn’t know a whole lot of black people, since, according to his spokesman, he wasn't aware the term was offensive. No big surprise there —neither Belmont, Massachusetts nor the LDS Church are teeming with African-Americans — but still worth mentioning.

Romney’s sure to embarrass himself again sometime in the next few months. In the meantime, here’s a recap of the stumbles that preceded the “tar baby” incident:

10) Cardinal error
As Romney heads to Rome for Boston archbishop Sean O’Malley’s elevation to cardinal in March, a Romney spokesperson says the two men are friends, and that the archbishop asked the governor to make the trip. But this doesn’t square with O’Malley’s account. “I’ve met him a couple times — don’t know him well,” the archbishop tells the Boston Globe. Worse, O’Malley says he didn’t invite the governor. (O’Malley’s spokesperson later says Romney did receive an invitation that “was similar to that extended to the general public.”)

9) The price is wrong
After the London subway bombings in July 2005, Romney briefly rides Boston’s T to reassure the citizenry. At a press conference beforehand, the governor incorrectly identifies the price of a subway token as $1. (It’s $1.25.)

8) What’s in a name?
During a radio appearance for the 2002 campaign, Romney forgets the name of his running mate, Kerry Healey. Explaining that Healey will help broaden the GOP ticket’s appeal, Romney says, “That is what has drawn me to Sherry.” Also, while discussing his efforts to woo conservative Democrats, Romney calls former Massachusetts governor and Reagan supporter Ed King “Frank King.”

BULLY FOR BU! | March 12, 2010 After six years at the Phoenix , I recently got my first pre-emptive libel threat. It came, most unexpectedly, from an investigative reporter. And beyond the fact that this struck me as a blatant attempt at intimidation, it demonstrated how tricky journalism's new, collaboration-driven future could be.

STOP THE QUINN-SANITY! | March 03, 2010 The year is still young, but when the time comes to look back at 2010's media lowlights, the embarrassing demise of Sally Quinn's Washington Post column, "The Party," will almost certainly rank near the top of the list.

RIGHT CLICK | February 19, 2010 Back in February 2007, a few months after a political neophyte named Deval Patrick cruised to victory in the Massachusetts governor's race with help from a political blog named Blue Mass Group (BMG) — which whipped up pro-Patrick sentiment while aggressively rebutting the governor-to-be's critics — I sized up a recent conservative entry in the local blogosphere.

RANSOM NOTES | February 12, 2010 While reporting from Afghanistan two years ago, David Rohde became, for the second time in his career, an unwilling participant rather than an observer. On October 29, 1995, Rohde had been arrested by Bosnian Serbs. And then in November 2008, Rohde and two Afghan colleagues were en route to an interview with a Taliban commander when they were kidnapped.

POOR RECEPTION | February 08, 2010 The right loves to rant against the "liberal-media elite," but there's one key media sector where the conservative id reigns supreme: talk radio.
